The MiurEssence dry sump system will be on display, installed on Miura 3486, at the Concorso Italiano on Friday, August 13, at Leguna Seca Golf Ranch, Monterey, California.
Advantages of the MiurEssence Dry Sump System
The Lamborghini Miura was conceptualized in a very short time by a handful of passionate
individuals, working on their own time, and inspired by their love of fast cars.
With strong public demand, the Miura was rushed to production without the testing
and verification we have come to expect today. One byproduct was a flawed oiling
system. Briefly, the problem is that, during moderate to extreme driving conditions,
the oil sloshes in the shallow oil pan and the oil supply to the engine is interrupted.
This causes extreme wear on the main rod and journal bearings. This problem is widely
known and well documented in numerous places. In Joe Sackey's book, The Lamborghini
Miura Bible, he quotes Anatoly Arutunoff, in part, "...Then I got a letter from
the factory saying they would upgrade it (his Miura P400) to an 'S' for a fixed
price, noting that the engines were only good for 40,000 miles!" Could that have
been caused primarily by the oil supply issues?
The MiurEssence Dry Sump System provides the following
advantages over the original Miura wet sump oiling system:
- It sustains uninterrupted oil pressure under virtually all driving conditions.
- The pan sits above the bottom of the frame (preventing potential bottoming damage).
- Oil stays in the filters when the engine is turned off (quicker oil pressure at
start-up).
- An electric pre-oil creates oil pressure before start-up.
- An external oil tank provides continuous oil supply.
- The system uses standard "spin on" oil filters that are available at local auto
parts stores.
- A screen in the windage tray catches potential debris.
- It works on both split sump and non-split sump engines.
- This bolt-on kit requires no permanent modifications to your Miura or its original
parts. (Original parts can be stored for potential future restoration to factory
specs.)
- An optional oil jet assembly provides pressurized oiling to the piston pins and gear train, camshaft sprocket
gears, and transfer case gear train (especially beneficial for split sump applications).
The MiurEssence Dry Sump System will improve the durability
of any Miura engine, partially offsetting the cost of the system through longer
engine life. When your engine is removed for maintenance or rebuild is the ideal time to install the MiurEssence
Dry Sump System.
